The abundant water in the rainy season is accommodated, stored and used appropriately throughout the year. The fact that is happening now as time goes by is that many reservoirs in Indonesia have decreased function and performance. One of them occurs in the Bajulmati Reservoir located in Banyuwangi and Situbondo districts, East Java. The decrease was due to the planning of the reservoir that was not in accordance with the current conditions. This study aims to analyze the Operating Pattern of Bajulmati Reservoir so that the reservoir is expected to provide optimal performance in utilization for irrigation, raw water and Micro Hydro Power Plants. This research was conducted by analyzing data for the availability and utilization of Bajulmati Reservoir water, stretching the discharge of reservoir inflow in the future for 50 years, forming a model with Dynamic Programming and simulation. The first simulation was carried out according to the operation of the current reservoir, which is prioritized for irrigation (factor kT = 100% with differences in how to calculate irrigation water requirements), irrigation water is passed through a turbine (PLTMH). In the second simulation, the reservoir was operated with the fulfillment of irrigation and raw water, a factor of kT> 70% and the Micro Hydro Power was optimized considering the availability of water in the reservoir. The simulation results show the operation of the reservoir in producing electricity on average per year if the turbine must be fully operational and if a turbine with a 20% maximum power already operate with a percentage of the fulfillment of irrigation and raw water (factor kT). From the analysis of income (without taking into account the cost and assuming the provision of irrigation water and raw water are performed simultaneously) are known to be the highest income and lowest income.

EFFECT OF THE LEAKAGE LOCATION PATTERN ON THE SPEED OF RECOVERY IN WATER SUPPLY NETWORKS Widyo Nugroho; Nur Iriawan Sepuluh November Institute of Technology (ITS) Abstract The International Water Association states that water loss is an efficient indicator of the performance of a water company that has been implemented internationally. The volume of water loss expressed as Non Revenue Water at the global level shows a high number. Every year more than 32 billion m3 of treated water is lost due to leakage from the distribution network. There are four pillars in a leak management strategy include management of pressure, speed of repair, active leakage control, and asset management. These factors influence how leakage is managed and thus the volume and value of economic leakage - in a distribution network of water companies. The Current Annual Volume of Physical Losses tends to increase along with the increasing service area of the distribution network. The rate of increase can be inhibited by the right combined strategy between the four components in an effective leakage management strategy. In this study, the factors that influence Non Revenue Water in water distribution system in Malang Town are analyzed by focusing on the speed of recovery aspect. With the expansion of service areas, the distribution of locations has an effect on the speed of recovery. In the end, the expected results of this study are to find the significance of the relationship between the distribution pattern of the location of damage to the water distribution network and the speed of recovery. The data in this study include historical data on the location of damage to the pipeline for 8 years which includes spatial data and historical data on the recovery of each damage in the form of attribute data. The method used in this study is the spatial point process. Poisson distribution in the spatial point process is chosen as the leakage location distribution approach. The results of the analysis state that the distribution pattern of leakage is inhomogeneous poisson process. Based on the model obtained by the simulation result, it is found that the effectiveness of the repair need to consider covariate location variable such as demand junction and border of District Metered Area.

CONFINEMENT INFLUENCE IN CRACKING AREAS SINGLE REINFORCED CONCRETE Eko Walujodjati, Ida Farida Sekolah Tinggi Teknologi Garut, Program Studi Teknik Sipil, jl. Mayor Syamsu No.1 Jayaraga, Garut, eko.walujodjati[at]sttgarut.ac.id Abstract Reinforced concrete as a building structure plays an important role in holding the load. The combination of concrete and reinforcement in collaboration with the load is determined by the perfect bond of the two materials. Bond testing on reinforced concrete has been carried out. The axial load is given in reinforced concrete results in internal cracking of reinforced concrete around the threaded reinforcement area. An area within the radius of cracking of the concrete around the reinforcement has also been obtained. The action is needed to reduce the area of cracked concrete by giving restraints using spherical spiral reinforcements within the concrete crack radius. It is expected to increase the strength of the reinforcement and concrete around it. The restraints using plain reinforcement in the area have been carried out. The methodology used is Pull Out on single reinforced concrete cylindrical specimens with confinement and without confinement. Concrete cylindrical test specimens with a diameter of 150 mm 200 mm high with single reinforcement with a diameter of 10 mm, and spiral reinforcement as confinement with an identification diameter of 4 mm and spacing of 22.5 mm and 45 mm. Placed within the radius of cracking of the concrete around the reinforcement. Pull out the test is carried out with gradual loading until it passes. The Pull Out test results indicate a fault movement from the edge that is loaded to the free end. The spiral coil of reinforcing steel as a restraint is relatively insignificant and increases strongly. The restrained specimen produces a larger fault at the end of the load, when the initial fault occurs at the free end, compared to the specimen without restraint. The difference in the increase in stickiness with the spiral spacing of steel reinforcement 22.5 mm and 45 mm has not been seen.

Effect of Using Geopolymer Flyash on Torsion Capacity of Hybrid High-Strength Reinforced Concrete Beams Containing Fine and Coarse Aggregates Substitution Which Added Iron Ores as Filler Teuku Budi Aulia (a*), Muttaqin (a), Mochammad Afifuddin (a), Muhammad Zaki (a), Geminingsih Nastiti (a) University of Syiah Kuala, Banda Aceh 23111, Indonesia *aulia[at]unsyiah.ac.id Abstract High demand for advanced infrastructure leads to the use of high strength concrete. Complex, futuristic and asymmetrical building construction could create dangerous torsional load and moment, mainly due to earthquake. Using large amount of cement makes high strength concrete not environmentally friendly. The use of natural aggregates continuously reduced its availability. Efforts to substitute cement and aggregate from abundant and environmentally friendly natural materials could be smart solution. This study aims to analyze the torsional capacity of high strength cantilever reinforced concrete beams having L configuration with a torque arm. Three hybrid beams were cast with substitution of 15% coal flyash (CFA), 15% palm oil blast furnace slag (POSFA) and 10% pozzolanic flyash (PFA) from cement weight, added with 10% pozzolanic sand as fine aggregate substitution and 40% palm oil blast furnace slag as coarse aggregate substitution. One beam without flyash and aggregate substitution (NPBHSC) was tested as comparison. All four beams added with iron ore as filler. The best torsion capacity achieved by PFA beam with maximum load (P) 2.83 ton, maximum torsion moment (M) 10.4 kNm, maximum torsion angle 0.0225 rad, ductility 3.941 and cylinder compressive strength 59.48 MPa, when compared to NPBHSC beam which produced P = 2.65 ton, M = 9.638 kNm, torsion angle 0.0069 rad, ductility 1.008 and compressive strength 44.40 MPa. POSFA beam followed then by CFA beam resulted in slightly smaller P and M, but generated greater compressive strength, maximum torsion angle and ductility than NPBHSC. It can be concluded that geopolymer flyash can increase compressive strength, torsion capacity and ductility of high strength reinforced concrete beams.

Some kind of Thermal Injection should be performed prior to implementing the operation of Pressure Build Up test, where the heat will lower the heavy oil reservoir fluid. Sensitivity of several parameters namely viscosity, permeability, porosity, and shut-in time were used in designing Pressure Build Up test. The model also has an outer boundary. This sensitivity would give various reservoir reach of the test or radius of investigation. The sensitivity test showed that viscosity influences more on radius investigation as compared to permeability, porosity, and shut-in time. Since the Pressure Build Up test must reach radial flow period before pressure transient arrives at the nearest boundary, the test scenarios with viscosity range from 5.602 to 24.796 cp were suitable for the well. Furthermore, the study was continued to correlate radius of investigation as a function of the parameters mentioned above. A constant value of the correlation obtained from this study was 1197.

This study identified the characteristics of pedestrian paths and green lanes in the center of Garut and evaluated the use of pedestrian paths and green lanes in cities. The method used is descriptive qualitative analysis. The perception of the community of pedestrian users was analyzed from the results of the questionnaire. Responden was chosen randomly from pedestrian and green lane users along Ahmad Yani road which is the center of Garut. The condition of the pedestrian path along the Ahmad Yani road from the Asian crossing to the Holy Bunderan was damaged in several points so that it disturbed the comfort of pedestrians. Circulation of pedestrians is also disturbed because some pedestrian spaces are actually used by street vendors to sell. The pedestrian facilities along Ahmad Yani Road are still incomplete and some of them are in damaged condition. Facilities that are damaged and not as needed are benches, lack of trash bins and non-lit lighting. Plants in open space which is a green path are in poorly maintained condition and even many die. Community perceptions of the importance of the existence of pedestrian lanes and green lanes also influence the awareness of the user community to help maintain and maintain pedestrian paths and green lanes in urban cities.

Strength Properties of Fly Ash Geopolymer Mortar Incorporating High Calcium Class C Fly Ash and Zeolit Arie Wardhono Department of Civil Engineering, Universitas Negeri Surabaya, Kampus Unesa Ketintang, Surabaya 60231, Indonesia ariewardhono[at]unesa.ac.id Abstract The use of fly ash as cement replacement material in geopolymer is able to overcome the environmental problems caused by the cement production process. One type of fly ash that is widely used is class C fly ash which has a high calcium content. However, the main issue of this materials is the low silicate content which is required in forming geopolymer matrix. The use of zeolite which has a high silicate content is one alternative to overcome this problem. This research aims to identify the effect of zeolit addition in strength of high calcium class C fly ash geopolymer mortar. The ratio of zeolit to fly ash was 5% : 95%, 10% : 90%, 15% : 85%, 20% : 80%, and 25% : 75%, respectively. The specimen was developed using the blended 12 molar NaOH and sodium silicate at room temperature. The results showed that the combination of 95% fly ash and 5% zeolit gives the highest compressive strength. The zeolit significantly affects the strength development rate of geopolymer and accelerates the setting time rate. This can be concluded that the mix of class C fly ash and zeolite can provide an alternative in geopolymer production at room temperature.
